Does anyone else experience split second blackouts?

I know it’s probably not me actually blacking out but having blacked out fully before it kinda feels like how it does right before I black out. Basically for not even a second (I don’t think) I’ll do this thing where everything feels fuzzy and it feels like I’m about to faint. When this happens externally I look completely normal like nothing’s happening. I’m curious as to if anyone has had this and what exactly it is

I'm guessing almost everyone has had this feeling, but probably for a lot of different reasons.  Sometimes lack of eating, sometimes lack of sleep, sometimes overwork, sometimes heat, sometimes, well, you get the picture.  Unfortunately, none of us can tell you why it's happening to you, but since you posted on the anxiety forum, if you're a chronically anxious person this can be a symptom of anxiety.  But if you truly have blacked out before, and not just say you blacked out -- a lot of especially young people use this term but don't mean it literally -- the question would be, why did it happen the time it did happen?  I'm assuming that if you truly suffer blackouts, true blackouts, you've had significant medical testing and diagnosis.
